LMV931-N - Single 1.8V, RRIO Operational Amplifiers

The LMV93x-N family (LMV931-N single, LMV932-N dual and LMV934-N quad) are low-voltage,low-power operational amplifiers. The LMV93x-N family operates from 1.8-V to 5.5-V supply voltagesand have rail-to-rail input and output. The input common-mode voltage extends 200 mV beyond thesupplies which enables user enhanced functionality beyond the supply voltage range. The output canswing rail-to-rail unloaded and within 105 mV from the rail with 600-Ω load at 1.8-V supply. TheLMV93x-N devices are optimized to work at 1.8 V, which make them ideal for portable two-cell,battery-powered systems and single-cell Li-Ion systems.

LMV93x-N devices exhibit an excellent speed-power ratio, achieving 1.4-MHz gain bandwidthproduct at 1.8-V supply voltage with very low supply current. The LMV93x-N devices can drive a600-Ω load and up to 1000-pF capacitive load with minimal ringing. These devices also have a highDC gain of 101 dB, making them suitable for low-frequency applications.

The single LMV93x-N is offered in space-saving 5-pin SC70 and SOT-23 packages. The dualLMV932-N are in 8-pin VSSOP and SOIC packages and the quad LMV934-N are in 14-pin TSSOP and SOICpackages. These small packages are ideal solutions for area constrained PC boards and portableelectronics such as mobile phones and tablets.
